在提交按钮单击登录详细信息后如何将用户重定向到主页

[英]how to redirect user to the home page after login details on submit button click

问题描述

Am trying to direct a user to admin dashboard after login if user name and password exist in the database.如果数据库中存在用户名和密码，我试图在登录后将用户引导到管理仪表板。 if not then direct user back to the login page.如果没有，则将用户引导回登录页面。 But is not working when the user enters his details instead of going to the admin dashboard page it is directed back to the login page even though users details are in the database.但是当用户输入他的详细信息而不是进入管理仪表板页面时不起作用，即使用户详细信息在数据库中，它也会被引导回登录页面。 The problem is with the admin-dashboard.php file if I comment out "header('location:index.php');"问题出在 admin-dashboard.php 文件中，如果我注释掉“header('location:index.php');” it works perfectly but user can access the admin-dashboard without logging in form the url search bar and i don't want that way它运行良好，但用户无需登录 url 搜索栏即可访问管理仪表板，我不希望这样

This is my index.php这是我的索引。php

    <?php
session_start();
if(isset($_SESSION['username'])){
   header('location:admin-dashboard.php');
    exit();
}
?>

I think you need your location header to be an absolute path with HTTP 1.1 as specified in the PHP documentation.我认为您需要您的位置 header 成为 PHP 文档中指定的 HTTP 1.1 的绝对路径。 header('Location: http://localhost/admin-dashboard.php'); or call within exit, exit(header('Location: http://localhost/admin-dashboard.php'));或在出口内调用， exit(header('Location: http://localhost/admin-dashboard.php'));

First of all fetch data from the database if the result is greater than 0 it redirects with the below code首先，如果结果大于 0，则从数据库中获取数据，它会使用以下代码重定向

<?php
require_once 'config.php';

//creating new object of admin class in admin-action.php
class Admin extends Database {
    // Admin login

    public function admin_login($username, $password)
    {
       $sql = "SELECT username,password FROM admin WHERE username = :username AND 
       password = :password";

       $stmt = $this->conn->prepare($sql);
       $stmt->execute(['username'=>$username,'password'=>$password]);
       $row = $stmt->fetch(PDO::FETCH_ASSOC);
if($row > 0){
header('location:index.php);
}else{
header('location:error.php);
}

  }
}
?>
